Application filed irebrna y 26, 1926. Serial No. 90,790.

. the wedge member may engage in moving to its holding position, saidsurface being mounted to move to adapt itselfqto a surface on the Wedge.Afurther object of the invention is to provide a novel means of movingthe wedge member toward and from holding position. v

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a fragmentary view of a sash and a window frame showing thesash holder in the position it occupies when the sash is free to move;

Fig. 2 is similar view showing the sash holder in holding position; and

Fig. 3 is a sectional view through the sash showing the sash holder inside elevation in the position illustrated in Fig. 1.

Referring more particularly to the drawings, 1 indicates the windowframe and 2 the sash. In this instance, the sash holder is illustratedas being mounted on the sash, but it will be understood that theinvention is not limited to this position. The holder, in this instance,embodies a wedge member 3 having two faces 4 and 5 at angles to eachother other than right angles. This wedge member may be moved toward andfrom wedging position by an eccentric 6 pivoted at 7, in this instance,to the sash and having an eccentric surface 8 cooperating with ashoulder 9formcd on the upper part of the wedge member. The wedge memberhas an extension 10 projecting above said shoulder which is adapted tolimit the movement of the eccentric 6 in one direction, the eccentric,in this instance, having an extension or operating arm 11 which isextended therefrom to cooperate with the extension 10. The eccentricsurface 8 cooperates with the shoulder 9 and depresses the wedge 3 toholding position. In order to withdraw the wedge from holding positionthe eccentric has a link 12 pivoted at an eccentric point 13 thereto andformed with a slot 15 whichreceives a headed projection 16 on the wedgemember. It is apparent that with the swinging of the eccentric 6 throughthe arm 11, the link 12 .will ride on the headed projection 16 throughthe slot 15, but with the swinging of the eccentric member upwardly, theend of the slot 15 will cooperate with the headed pro jection 16 andelevate the wedge member 3.

The wedge member preferably cooperates with .a block or member 17 whichhas a straight line face 18 cooperating with the straight line face 5 ofthe wedge member 3. The straight line face 18 is arranged at an angleother than a right angle to the line of movement of the sash and this isalso true of the straight line face 5 of the wedge member. The straightline face 4 of the wedge member is substantially parallel with the lineof movement of the sash. The member. 17 is pivoted at 19 between the twoends of its straight line. face preferably to the sash 2. As aconsequence, the member 17 rocks on the pivot 19 and the face 18 adaptsitself to the position of the wedge member. This arrangement makes itunnecessary to accurately position the member 17 on the sash and makesit possible to obtain binding engagement between the wedge member 3 andthe member 17 throughout the length of the two cooperating faces, while,at the same time, obtaining binding engagement between the member 3 andthe part of the window having relative movement to said member, so thatthe face 4 of the member 3 will lie parallel with the surface with whichsaid member engages to hold the sash against movement.

In order to permit the free movement of the sash, the operatingeccentric or cam 7 is moved to the position shown in Fig. 1, drawing thewedge member 3 upwardly and away from the frame of the window. To holdthe window sash in an adjusted posi tion the cam or eccentric 6 isturned through V the arm 11 to the position shown in Fig. 2, forcing thewedge member downwardly into engagement with the face 18 of the member17 and with the adjacent position of the window frame. o

What I claim as my invention and desire to secure by Letters Patent is:

1. A sash holder comprising a wedge having two surfaces at angles toeach other other than right angles, one of said surfaces being adaptedto cooperate with a part to hold the sash in an adjusted position, arocking member having a straight line surface for co-' operating withthe other surface of the Wedge when the latter is in holding positionand means for moving said wedge into engagement with the rocking memberincluding a pivoted eccentric engaging said wedge.

2. A sash holder comprising a wedge having two surfaces at angles otherthan rightangles to each other, one of said surfaces acting to engage apart to hold the sash in adjusted position, another member having asurface adapt-ed to be engaged by the other surface of the wedge whenthe wedge is in holding position, and means for-operating said wedgecomprising an eccentric having a portion adapted to engage the wedge,and a link pivotally connected to the eccentric at a point eccentric tothe turning-axis of the latter and having a pin and slot connectionwit-h the wedge member.

-' and having an arm adapted to cooperate with the extension on thewedge member to limit the movement of the eccentric in one direction, aconnecting linkbetween the eccentric and the wedge memberfor moving thelatter awayfrom holding position, and a member cooperating with theother face of the wedge member to force the wedge member into engagementwith a part to hold the sash against movement.
